Does he like me more than a friend?

when playing bowling, he supports me most of the time by clapping or saying good job. he handshakes me only. when talking to me and my friend, he mostly looks at my friend and he just glances at me. today, he acted weird... he was not so talkative but when we walk he sticks next to me. his hand was sweaty today when he gave me a goodbye handshake. he almost always goes everywhere where i invite him. he offered me to teach me how to ice skate and he helped me out with chemistry homework. and we dont talk so much because he has limited sms and i dont wana call him. so what do you think?
